Safety information
Electrical safety
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before
relocating the system.
When adding or removing devices to or from the system, ensure that the power cables for the devices
are unplugged before the signal cables are connected. If possible, disconnect all power cables from
the existing system before you add a device.
Before connecting or removing signal cables from the motherboard, ensure that all power cables are
unplugged.
Seek professional assistance before using an adapter or extension cord. These devices could interrupt
the grounding circuit.
Make sure that your power supply is set to the correct voltage in your area.
If you are not sure about the voltage of the electrical outlet you are using, contact your local power
company.
If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or
your local distributor.
Operation safety
Before installing the motherboard and adding devices on it, carefully read all the manuals that came
with the package.
Before using the product, make sure all cables are correctly connected and the power cables are not
damaged. If you detect any damage, contact your dealer immediately.
